The code will be the same because the components you use in LabVIEW are abstracted for each library (IMAQ for the cRio/laptop and OpenCV for the laptop). For instance if you use some sort of rectangle detector block, LabVIEW will know whether to use IMAQ or OpenCV based on the target platform - your code remains the same.

If you're using your Classmate as the DS and want to do the processing on there, I assume you'd use the dashboard data (there should be examples in LabVIEW, there are in C++).

I'm still wondering how to do it between the cRio and a laptop on the robot.

EDIT:

To take advantage of this and distribute the processing, you need to send the image from the robot to the dashboard laptop, process it, and then send the results back to the robot. Transmitting data and images also takes time, so the best location to process images depends on all of these factors. You may want to take measurements or experiment to determine the best approach for your team.

This is the quote from NI's document, so yes you'll have to use the dashboard data example.
